ObolNetwork/charon v0.9.0 on GitHub

This is a non-urgent release introducing general fixes and improvements.

#710 adds a Timestamp field to the cluster definition file making it easier to identify for humans. The new definition version is v1.1.0, the previous v1.0.0 definition version is however still supported.
#552 adds support for multiple beacon nodes leveraging go-eth2-client's multiclient feature. The --beacon-node-endpoint flag is deprecated in favour of --beacon-node-endpoints that support a comma separated list of beacon nodes.
#764 introduces an experimental alpha feature that attempts to sync slot scheduling with the beacon node clock using event stream head events. It can be enabled with --feature-set=alpha or feature-set-enable=beacon_clock_sync flags. Note even if not enabled, the clock offset can be monitored via the prometheus metric core_scheduler_beacon_node_offset_seconds.
#781 pushes docker images to Dockerhub, so docker pull obolnetwork/charon:v0.9.0 also works now. Note previous versions have not been backfilled though. Dockerhub provides slightly better UX than Github Container Registry since no login is required.
